how to get developer options in 4,3 update

[le_Bob]

Settings >about Phone> tap "build number" often until it comes a message that you are a developer now, go back to settings and the developer options will be there

go to Settings-about phone-tap about 6-7 times on the build number u will get wht u need

Hi Chinnav

The Illumunation bar effect is something which is being bugging all the users after the update , the beat effects works with low volume and glow on high volume.. May be the next firmware update which is on cards might fix the bugs.. if anything other than the illumination bar is bugging you then recommend you to perform reset factory settings

Download a 3rd party app for the illumination bar.
